EulerOS Virtualization 2.11.0 : protobuf (EulerOS-SA-2026-3541)

high Nessus Plugin ID 347219

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the protobuf packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 Any project that uses Protobuf Pure-Python backendto parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUPtags can be corrupted by exceeding the Python recursion limit. This can result in a Denial of service by crashing the application with a RecursionError. We recommend upgrading to version =6.31.1 or beyond commit17838beda2943d08b8a9d4df5b68f5f04f26d901(CVE-2025-4565)

 A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, where the max_recursion_depth limit can be bypassed when parsing nested google.protobuf.Any messages.Due to missing recursion depth accounting inside the internal Any-handling logic, an attacker can supply deeply nested Any structures that bypass the intended recursion limit, eventually exhausting Python's recursion stack and causing a RecursionError.(CVE-2026-0994)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization protobuf security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected protobuf packages.
